My curriculum vitae.

I am an assistant professor in the Department of Mathematics, Rutgers University — New Brunswick.

I obtained my Ph.D. in Mathematics at Stanford University in 2016, and conducted postdoctoral research at Columbia University as a Junior Fellow of the Simons Society of Fellows, from 2016 to 2019.

My research interest lies in probability theory, particularly asymptotic behaviors of large interacting particle systems, with a focus on their interplay between partial differential equations, stochastic partial differential equations, and integrable probability.
